Safety Precautions and
Working Techniques
Because a clearing saw is a high-speed, fast-cut- ting power tool sometimes equipped with sharp cutting blades, special safety precau- tions must be observed to reduce the risk of per- sonal injury.
It is important that you read, fully understand and observe the following safety precautions and warnings. Read the instruction manual and the safety precautions periodically. Careless or improper use may cause serious or fatal injury.
The terminology utilized in this manual when referring to the power tool reflects the fact that different types of cutting attachments may be mounted on it. The term "trimmer" is used to designate an FS unit thatisequippedwith anylonline head or a head with flexible plastic blades (i.e., the PolyCut head). A "brushcutter" designates a unit equipped with a rigid metal blade. Many FS models may be used as either a trimmer or a brushcutter – therefore, the powertoolisreferredinthismanualasa "trimmer / brushcutter." Some smaller and / or lightweight FS models may only be used as a trimmer, i.e., they may not be used with metal blades.
The term "clearing saw" indicates a high-powered trimmer / brushcutter that is particularly suited for use with a circular saw blade to clear saplings or small trees.
WARNING
As more fully explained later in these Safety Precautions, to reduce the risk of personal injury, make sure your unit is equipped with the proper deflector, limit stop and harness for the type of cutting attachment you are using. Use only cutting attachments that are specifically authorized by STIHL for use on your FS model.
Have your STIHL dealer show you how to operate your power tool. Observe all applicable local safety regulations, standards and ordinances.
WARNING
Do not lend or rent your power tool without the instruction manual. Be sure that anyone using it understands the information contained in this manual.
WARNING
The use of this machine may be hazardous. If the rotating line or blade comes in contact with your body, it will cut you. When it comes in contact with solid foreign objects such as rocks or bits of metal, it may fling them directly or byricochetinthedirectionofbystanders or the operator. Striking such objects could damage the cutting attachment and may cause blades to crack, chip or break.Thrownobjects,including broken headsorblades,mayresultinseriousor
English
fatalinjurytotheoperatororbystanders. STIHL does not recommend the use of rigid blades when cutting in stony areas.
Useyourclearingsawequippedwiththe appropriate cutting attachment only for cutting grass, brush, wood and similar material.
WARNING
Do not use it for other purposes, since misuse may result in personal injury or property damage, including damage to the machine.
WARNING
Minors should never be allowed to use this power tool. Bystanders, especially children, and animals should not be allowed in the area where it is in use.
WARNING
Toreducetheriskofinjurytobystanders and damage to property, never let your power tool run unattended. When it is not in use (e.g. during a work break), shut it off and make sure that unauthorized persons do not use it.
Most of these safety precautions and warnings apply to the use of all STIHL clearing saws. Different models may have different parts and controls. See the appropriate section of your instruction manual for a description of thecontrols and thefunctionofthe parts of your model.
Safe use of a clearing saw involves

THE OPERATOR
Physical Condition
You must be in good physical condition and mental health and not under the influence of any substance (drugs, alcohol, etc.) which might impair vision, dexterity or judgment. Do not operate this machine when you are fatigued.
WARNING
Be alert – if you get tired, take a break. Tiredness may result in loss of control. Working with any power tool can be strenuous.Ifyouhaveanyconditionthat mightbeaggravatedbystrenuouswork, check with your doctor before operating this machine.
WARNING
Prolonged use of a power tool (or other machines) exposing the operator to vibrations may produce whitefinger disease (Raynaud's phenomenon) or carpal tunnel syndrome.
These conditions reduce the hand's ability to feel and regulate temperature, produce numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.
All factors which contribute to whitefinger disease are not known, but cold weather, smoking and diseases or physical conditions that affect blood vessels and blood transport, as well as high vibration levels and long periods of
4
exposure to vibration are mentioned as factorsinthedevelopmentofwhitefinger disease. In order to reduce the risk of whitefinger disease and carpal tunnel syndrome, please note the following:
–Most STIHL power tools are available with an anti-vibration ("AV") system designed to reduce the transmission of vibrations created by the machine to the operator's hands. An AV system is recommended for those persons using power tools on a regular or sustained basis.
–Wear gloves and keep your hands warm.
–Keep the AV system well maintained. A power tool with loose components or with damaged or worn AV elements will tend to have higher vibration levels.
–Maintain a firm grip at all times, but do not squeeze the handles with constant, excessive pressure. Take frequent breaks.
All the above-mentioned precautions do not guarantee that you will not sustain whitefinger disease or carpal tunnel syndrome. Therefore, continual and regular users should closely monitor the condition of their hands and fingers. If any of the above symptoms appear, seek medical advice immediately.
WARNING
The ignition system of the STIHL unit produces an electromagnetic field of a very low intensity. This field may interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with a pacemaker should
consult their physician and the pacemaker manufacturer before operating this tool.
Proper Clothing
To reduce the risk of injury, the operator should wear proper protective apparel.
WARNING
The deflector provided with your power tool will not protect the operator from all foreign objects (gravel, glass, wire, etc.) thrown back by the rotating cutting attachment. Thrown objects may also ricochet and strike the operator.
WARNING
To reduce the risk of injury to your eyes never operate your power tool unlesswearinggogglesor
properly fitted protective glasseswithadequatetop andsideprotectioncomplyingwithANSI
Z 87.1 (or your applicable national standard). To reduce the risk of injury to your face STIHL recommends that you also wear a face shield or face screen over your goggles or protective glasses.
Wear an approved safety hard hat to reduce the risk of injury to your head when there is a danger of head injuries.
Power tool noise may damage your hearing. Wear sound barriers (ear plugs or ear mufflers) to protect your hearing. Continualandregularusersshouldhave their hearing checked regularly.
Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.
FS 510 C-M, FS 560 C-M
Always wear gloves when handling the machine and metal blades. Heavy-duty, non- slip gloves improve your grip and help to protect your hands.
Clothing must be sturdy and snug-fitting, but allow
complete freedom of movement. Wear long pants made of heavy material to help protect your legs. Do not wear shorts, sandals or go
barefoot.
Avoid loose-fitting jackets, scarfs, neckties, jewelry, flared or cuffed pants, unconfined long hair or anything that could become caught on branches, brush or the moving parts of the unit. Secure hair so it is above shoulder level.
Good footing is very important. Wear sturdy boots with nonslip soles. Steel-toed safety boots are recommended.
THE POWER TOOL
For illustrations and definitions of the power tool parts see the chapter on "Main Parts."
WARNING
Nevermodifythispowertoolinanyway. Only attachments supplied by STIHL and expressly approved by STIHL for use with the specific STIHL model are authorized. Although certain
unauthorized attachments are useable with STIHL power tools, their use may, in fact, be extremely dangerous. For the cutting attachments authorized by STIHL for your unit, see the chapter "Approved Combinations of Cutting Attachment, Deflector, Limit Stop and Harness"intheinstructionmanualorthe STIHL "Cutting Attachments, Parts & Accessories" catalog.
If this tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work.Checkin particularthat the fuel system is tight (no leaks) and that the controls and safety devices are working properly. Do not continue operating this machine if it is damaged. Incaseofdoubt,haveitcheckedbyyour STIHL servicing dealer.

burn injury or property damage. Use extreme caution when handling gasoline or fuel mix. Do not smokeorbringanyfireorflamenearthe fuel or the power tool. Note that combustiblefuelvapormayescapefrom the fuel system.
Fueling Instructions
WARNING
To reduce the risk of serious injury from burns, never attempt to refuel the unit until it has been completely removed from the operator.
WARNING
Fuel your power tool in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refueling. Gasoline vapor pressure may build up inside the fuel tank depending on the fuel used, the weather conditions and the tank venting system.
In order to reduce the risk of burns and other personal injury from escaping gas vapor and fumes, remove the fuel filler capon yourpowertool carefully so asto allow any pressure build-up in the tank to release slowly. Neverremovethe fuel filler cap while the engine is running.
Selectbare groundforfuelingandmove at least 10 feet (3 m) from the fueling spot before starting the engine. Wipe off any spilled fuel before starting your machine.
WARNING
Check for fuel leakage while refueling and during operation. If fuel leakage is found, do not start or run the engine until the leak is fixed and
any spilled fuel has been wiped away. Take care not to get fuel on your clothing. If this happens, change your clothing immediately.
Screw Cap
WARNING
Unit vibrations can cause an improperly tightened fuel filler cap to loosen or
come off and spill quantities of fuel. In order to reduce the risk of fuel
spillageandfire,tightenthefuelfillercap by hand as securely as possible.
See also the "Fueling" chapter in your Instruction Manual for additional information.
Before Starting
WARNING
Alwayscheck yourpowertool forproper condition and operation before starting, particularly the throttle trigger, throttle trigger lockout, momentary stop switch, cutting attachment, deflector and harness. The throttle trigger must move
freely and always spring back to the idle position. Never attempt to modify the controls or safety devices.
WARNING
Never operate your power tool if it is damaged, improperly adjusted or maintained, or not completely or securely assembled.
WARNING
Do not attach any cutting attachment to a unit without proper installation of all required parts. Failure to use the proper parts may cause the blade or head to fly off and seriously injure the operator or bystanders.
WARNING
Thecuttingattachmentmustbeproperly tightened and in safe operating condition. Inspect for loose parts (nuts, screws, etc.) and for cracked or damaged heads or cracked, bent, warped or damaged blades. Replace damaged heads or blades before using the power tool. Always keep blades sharp.
Keep the handles clean and dry at all times; it is particularly important to keep themfreeofmoisture,pitch,oil,fuelmix, grease or resin in order for you to maintain a firm grip and properly control your power tool.

English
cuttingattachmentismorefullyexposed and the power tool may be more difficult to control. Never use your clearing saw as a hedge trimmer.
WARNING
During cutting, check the tightness and theconditionofthecuttingattachmentat regular short intervals with the engine and attachment stopped. If the behavior of the attachment changes during use, stop the engine immediately, wait until the cutting attachment stops, and check the nut securing the attachment for tightness and the blade or head for cracks, wear and damage.
WARNING
A loose blade or head may vibrate, crack, break or come off the clearing saw, which may result in serious or fatal injury. Make sure that the cutting attachment is properly tightened. Use the wrench supplied or one of sufficient length to obtain the proper torque. If the blade or head loosens after being properly tightened, stop work immediately. The retaining nut may be worn or damaged and should be replaced. If the blade or head continues toloosen,seeyourSTIHLdealer.Never use a clearing saw with a loose cutting attachment.
WARNING
Replace a cracked, damaged or wornout head or a cracked, bent, warped, damaged, dull or worn out blade immediately,evenifdamageislimitedto superficial cracks. Such attachments may shatter at high speed and cause serious or fatal injury.
WARNING
When using rigid blades, avoid cutting close to fences, sides of buildings, tree trunks, stones or other such objects that could cause the power tool to kick out or could cause damage to the blade.
STIHLrecommendsuseofthenylonline heads for such jobs. In addition, be alert toanincreasedpossibilityofricochetsin such situations.
WARNING
If the head, blade or deflector becomes clogged or stuck, always shut off the engine and make sure the cutting attachment has stopped before cleaning. Grass, weeds, etc. should be cleaned off the blade or from around the head at regular intervals.
WARNING
To reduce the risk of unintentional rotation of the cutting attachment and injury, always shut off the engine and remove the spark plug boot before replacing the cutting attachment. To reduce the risk of injury, always shut off theenginebeforeadjustingthelengthof the nylon line on manually adjustable mowing heads.
WARNING
Do not turn the engine on over the starter with the spark plug boot or spark plug removed since there is otherwise a risk of fire from uncontained sparking.
WARNING
The gearbox becomes hot during operation. To reduce the risk of burn injury, do not touch the gear housing when it is hot.
WARNING
Never modify your muffler. Any modification could cause an increase in heat radiation, sparks or sound level, thereby increasing the risk of fire, burn injury or hearing loss. You may also permanently damage the engine. Have your muffler serviced and repaired by your STIHL servicing dealer only.
WARNING
Themufflerandotherpartsoftheengine (e.g. fins of the cylinder, spark plug) becomehotduringoperationandremain hot for a while after stopping the engine. Toreduceriskofburns,donottouchthe muffler and other parts while they are hot. Keep the area around the muffler clean. Remove excess lubricant and all debris such as pine needles, branches or leaves. Let the engine cool down sitting on concrete, metal, bare ground or solid wood (away from any combustible substances.
WARNING
An improperly mounted or damaged cylinder housing or a damaged/deformed muffler shell may interfere with the cooling process of the muffler. To reduce the risk of fire or burn injury, do not continue work with a damaged or improperly mounted cylinder housing or a damaged/deformed muffler shell.

FS 510 C-M, FS 560 C-M |
Your muffler is furnished with a spark arresting screen designed to reduce the risk of fire from the emission of hot particles. Never operate your unit with a missing or damaged spark arresting screen.Ifyourgas/oilmixratioiscorrect (i.e., not too rich), this screen will normally stay clean as a result of the heat from the muffler and need no service or maintenance. If you experiencelossofperformanceandyou suspect a clogged screen, have your muffler maintained bya STIHLservicing dealer. Some state or federal laws or regulations may require a properly maintained spark arrestor for certain uses.Seethe"Maintenance,Repairand Storing" section of these Safety Precautions. Remember that the risk of a brush or forest fire is greater in hot or dry conditions.
WARNING
Some STIHL power tools are equipped with a catalytic converter, which
is designed to reduce the exhaust emissions of the engine by a chemical
process in the muffler. Due to this process, the muffler does not cool down asrapidlyasconventionalmufflerswhen the engine returns to idle or is shut off. To reduce the risk of fire and burn injurieswhenusingacatalyticconverter, always set your power tool down in the upright position and never locate it where the muffler is near dry brush, grass, wood chips or other combustible materials while it is still hot.
USING THE CUTTING ATTACHMENT
For an illustration of the various cutting attachments and instructions on proper mounting see the chapter on "Mounting the Cutting Attachment" in your instruction manual.
WARNING
To reduce the risk of severe or fatal injury from blade contact and / or loss of control, never attempt to use a metal blade on an FS model for which it is not authorized.
Using the Mowing Heads
Do not use with mowing line longer than the intended length. With a properly mounted deflector, the built-in linelimiting blade will automatically adjust the line to its proper length.
Using the unit with an overly long nylon cutting line increases the load on the engineandreducesitsoperatingspeed. This causes the clutch to slip continuously and results in overheating and damage to important components (e.g. clutch, polymer housing components). Such damage could, among other things, cause the cutting attachment to rotate at idle.
English
002BA354 KN
Mowing heads are to be used only on clearing saws equipped with a linelimiting blade in the deflector in order to keep the line at the proper length (see "Main Parts" chapter in your instruction manual).
If the lawn edges are planted with trees or bordered by a fence etc., it is best to use a nylon line head. It achieves a "softer" cut with less risk of damaging tree bark etc. than polymer blades.
However, the polymer-bladed STIHL PolyCut produces a better cut if there arenoplantsalongtheedgeofthelawn. Sharpening is not necessary, and worn polymer blades are easily replaced.
WARNING
To reduce the risk of serious injury, never use wire or metal-reinforced line or other material in place of the nylon cutting lines. Pieces of wire could break off and be thrown at high speed toward the operator or bystanders.
STIHL AutoCut mowing head
Nylon cutting line advances automatically when tapped against the ground (TapAction).

STIHL TrimCut mowing head
Frayed line is replaced by a simple adjustment (see instruction sheet supplied with mowing head).
STIHL PolyCut mowing head
002BA396 KN
Uses either nylon lines or nonrigid, pivoting polymer blades.
Observe wear indicators.
WARNING
Three rectangular wear limit marks are applied to the base (periphery) of the PolyCut. To reduce the risk of serious injury from breakage of the head or blades, the PolyCut must not be used when it has worn as far as one of these marks. It is important to follow the maintenance instructions supplied with the head.
WARNING
Ifthewearlimitmarksareignored,there is a risk of the cutting attachment shattering and flying parts injuring the operator or bystanders. To reduce the risk of accidents from shattered blades, avoid contact with stones, metal and similar solid objects. Check PolyCut bladesforcracksatregularintervals.Ifa crack is found on one blade, always replace all blades.
Risk of Kickout (Blade Thrust) with all Rigid Cutting Blades
002BA135 KN
WARNING
Kickout (blade thrust) is the sudden and uncontrolled motion towards the operator's right or rear that can occur when the shaded area (especially the darkly shaded area) of a rotating blade comesin contactwitha solid rigid object like a tree, rock, bush or wall. The rapid counterclockwise rotation of the blade may be stopped or slowed, and the cuttingattachmentmaybe throwntothe right or to the rear.
This kickout (blade thrust) may cause lossofcontrolofthepowertoolandmay result in serious or fatal injury to the operator or bystanders. To reduce the risk of injury, extreme caution should be used when cutting with the shaded area of any rigid blade.
Using the Grass Cutting Blade
002BA355 KN
All kinds of grass and weeds can be easily cut with the grass cutting blade. The power tool is swept in an arc similar to a scythe.
WARNING
To reduce the risk of serious or fatal injury from blade breakage, never attempt to use this blade to cut woody materials.
The 4-tooth grass cutting blade is intended to cut grass and weeds. It has 4 cutting knives with cutting edges on both sides, i.e. front and rear. When the cutting edges on one side become dull, the blade can be turned over to utilize the cutting edges on the other side.
The 8-tooth grass cutting blade is recommended for cutting fern or reed.
Bothtypesofgrasscuttingbladehaveto be resharpened when all cutting edges are dull.
Using the Brush Knife
When fitted to the power tool, the brush knife is suitable for applications ranging from cutting matted grass to clearing weeds, wild growth and scrub.
12 |
FS 510 C-M, FS 560 C-M |
002BA509 KN |
To cut wild growth and scrub, lower the rotating brush knife down onto the growth to achieve a chopping effect – but keep the tool below waist height at all times.
WARNING
Exercise extreme caution when using this method of cutting. The higher the cutting attachment is off the ground, the greater the risk of loss of control and of cuttings being thrown sideways.
Use the power tool like a scythe to cut grass, i.e. sweep it to and fro in an arc.
WARNING
When cutting woody materials, use the left side of the blade to avoid "kickout" (blade thrust) situations.
WARNING
Improperuseofabrushknifemaycause it to crack, chip or shatter. Thrown blade fragments may seriously or fatally injure the operator or bystanders. To reduce the risk of injury, avoid contact with hard or solid foreign objects such as stones, rocks or pieces of metal.
FS 510 C-M, FS 560 C-M
WARNING
When cutting young saplings or other woody materials up to 2 cm (3/4 in.) in diameter,usetheleftsideofthebladeto avoid "kickout" situations (see section on "Risk of kickout (blade thrust) with all rigid cutting blades"). Do not attempt to cut woody material with a larger diameter, since the blade may catch or jerk the power tool forward. This may causedamagetothebladeorpowertool or loss of control of the power tool, resulting in personal injury. Use a circular saw blade for such work.
WARNING
Inspect the brush knife at regular short intervals for signs of damage. Do not continue working with a damaged brush knife. Resharpen the brush knife regularly (when it has dulled noticeably).
Using the Circular Saw Blade
002BA067 KN
Circular saw blades are suitable for thinningbrushandcuttingsmalltreesup to a diameter of 7 cm (2 3/4 in.). Do not attempt to cut trees with larger diameters, since the blade may catch or jerk the trimmer / brushcutter forward. This may cause damage to the blade or loss of control of the power tool and result in serious injury. Use a chain saw for such work.
English
WARNING
To reduce the risk that the blade will crack and / or break, avoid all contact with stones, rocks or the ground.
Sharpen blades in a timely manner as specified – dull teeth may cause the blade to crack or shatter.
When a clearing saw with a circular saw blade is used to cut down small trees, STIHL recommends that the standard deflector be removed and replaced by the special limit stop deflector (see chapter on "Mounting the Deflector"). This limit stop helps to keep the unit positioned against the tree during the cutting process. Inexperienced users should place the left side of the stop against the tree trunk before beginning to cut. This will keep the clearing saw against the tree during the cutting operation and will reduce the risk of loss of control and possible kickout (described above and briefly again below).
002BA214 ST
Before starting the cut, accelerate the engine up to full throttle. Perform cut with uniform pressure. STIHL recommends that the circular saw blade be applied to the right of the tree, using the non-shaded area of the blade, as shown in the illustration above.
13
English
002BA068 KN
WARNING
The risk of kickout is highest when cutting in the darker shaded area. To reduce the risk of kickout and resulting injury,donotusethisareaofthecircular saw blade for cutting trees or shrubs. Special techniques using the lighter shaded areas of the blade to cut shrubs and trees should only be used by experienced operators with specialized training in the use and control of the clearing saw.
When felling small trees, maintain a distanceofatleasttwotreelengthsfrom the nearest coworker.
WARNING
In order to reduce the risk of injury from thrown objects or operator contact with the blade or head, be sure to remount the standard deflector when no longer using a circular saw blade.
MAINTENANCE, REPAIR AND STORING
Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However, if you make a warranty claim for a component which
14
has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny coverage.
WARNING
Use only identical STIHL replacement partsformaintenanceandrepair.Useof non-STIHL parts may cause serious or fatal injury.
Strictly follow the maintenance and repair instructions in the appropriate sections of your instruction manual.
WARNING
Always stop the engine and make sure that the cutting attachment is stopped before doing any maintenance or repair work or cleaning the power tool. Do not attempt any maintenance or repair work notdescribedinyourinstructionmanual. Have such work performed by your STIHL servicing dealer only.
Wear gloves when handling or performing maintenance on blades.
WARNING
Use the specified spark plug, and make sure it and the ignition lead are always clean and in good condition. Always press the spark plug boot snugly onto the spark plug terminal of the proper size. (Note: If the terminal has a detachable SAE adapter nut, it must be securely attached.) A loose connection between the spark plug and the ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.
WARNING
Never test the ignition system with the spark plug boot removed from the spark plugorwitharemovedsparkplug,since uncontained sparking may cause a fire.
WARNING
Do not operate your power tool if the mufflerisdamaged,missingormodified. An improperly maintained muffler will increasetheriskoffireandhearingloss. Your muffler is equipped with a sparkarresting screen to reduce the risk of fire; never operate your power tool if the screen is missing, damaged or clogged. Remember that the risk of a brush or forest fire is greater in hot or dry weather.
In California, it is a violation of § 4442 or § 4443 or the Public Resources Code to use or operate gasoline-powered tools on forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a complying spark arrester that is maintained in effective working order. The owner/operator of this product is responsible for properly maintaining the spark arrester. Other states or governmentalentities/agencies,suchas the U.S. Forest Service, may have similar requirements. Contact your local fire agency or forest service for the laws or regulations relating to fire protection requirements.
WARNING
Never repair damaged cutting attachmentsbywelding,straighteningor modifying the shape. This may cause parts of the cutting attachment to come off and result in serious or fatal injuries.
FS 510 C-M, FS 560 C-M
English
Keep blades sharp. Tighten all nuts, bolts and screws after each use.
Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine.
Store the power tool in a dry and high or locked location out of reach of children.
Before storing for longer than a few days, always empty the fuel tank. See chapter "Storing the Machine" in the instruction manual.

Fuel
This engine is certified to operate on unleaded gasoline and STIHL twostroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of highquality gasoline and two-stroke air cooled engine oil.
Usemid-gradeunleadedgasolinewitha minimum octane rating of 89 (R+M/2) and no more than 10% ethanol content.
Fuel with a lower octane rating may increase engine temperatures. This, in turn, increases the risk of piston seizure and damage to the engine.
The chemical composition of the fuel is also important. Some fuel additives not only detrimentally affect elastomers (carburetor diaphragms, oil seals, fuel lines,etc.),butmagnesiumcastingsand catalytic converters as well. This could cause running problems or even damage the engine. For this reason STIHL recommends that you use only high-quality unleaded gasoline!
Use only STIHL two-stroke engine oil or equivalent high-quality two-stroke engine oils that are designed for use only in air cooled two-cycle engines.
WerecommendSTIHLHPUltra2-Cycle Engine Oil since it is specially formulated for use in STIHL engines.
Do not use BIA or TCW rated (twostroke water cooled) mix oils or other mixoilsthatstatetheyareforuseinboth water cooled and air cooled engines (e.g., outboard motors, snowmobiles, chain saws, mopeds, etc.).
Take care when handling gasoline. Avoid direct contact with the skin and avoid inhaling fuel vapor. When filling at the pump, first remove the container from your vehicle and place the containeronthegroundbeforefilling.To reduce the risk of sparks from static discharge and resulting fire and/or explosion, do not fill fuel containers that are sitting in or on a vehicle or trailer.
The container should be kept tightly closedinordertolimittheamountofany moisture that gets into the mixture.
The machine‘s fuel tank should be cleaned as necessary.
Fuel mix ages
Only mix sufficient fuel for a few days work,nottoexceed3monthsofstorage. Store in approved fuel-containers only. When mixing, pour oil into the container first, and then add gasoline. Close the container and shake it vigorously by hand to ensure proper mixing of the oil with the fuel.
